How to synchronize two stream for stereo vision

[Damien Picard]

Hi !

I'm currently designing webcams that I will use with some stereo image
processing algorithms.

I'm streaming from an UVC cam through a RaspberryPi using vl42src,jpegdec,
omxh264 and gdp payload at 15 fps in 1920x1080 and it works fine.

Now, I want to synchronize, as much as possible, two streams coming from
two such cameras. To do that, I think I have to use some timestamps
informations (PTS, DTS, etc.) but I see that these timestamps are always
relative to the beginning of the stream.
Is it possible to add an "absolute" timestamp to a payload (GDP payload or
any other) ? Even if only to add some absolute timestamps every 5 seconds,
or something like that ?

Thank you.
